AUTOMATIC VALVE-CLOSER.

Application filed August 5, 1919. Serial No. 315,444.

new and useful Improvements in Automatic Valve-Closers, of which the following is a specification.

This invention relates to an automatic valve closer for a gas burner. Its organization comprises a valve for the tip end of a gas burner that is actuated by a sprlng that is caused to expand and elongate by the heat of the light of the burner.

In the drawings, Figure 1 is an elevation of an exemplification of the valve closer with its gas burner; Fig. 2 is a lefthand view of Fig. 1; Fig. 3 represents an enlarged section of Fig. 1' on the line 3, 3; Fig. 4 shows a section of Fig. 3 on the line 4, 4 and Fig. 5 represents a section of Fig. 3 on the line 5, 5.

A gas burner is provided with the usual tip 21 having the gas tip 22. The tip end 21 has formed in its wall the opening 25 which with the top wall 26 and the bottom wall 27 forms the chamber 28 in the said tip end. In a portion of the wall of the tip end 21 a port 30 is formed with the inlet opening 31 and the outlet opening 32. The port 30 constitutes a by-pass port around the chamber 28.

A third wall 33 with the ports 34 extends across the bore of the tip end 21. A valve seat 35 is formed with the wall of the tip end 21. A valve has extending from its lower face the guide plug 41 having the ports 42. p A valve spindle 43 with the cap 44 extends from the upper face of the valve 40, and a guide pin 45 extends from the lower face of the guide plug 41. A bracket 46 has its lower end fastened to the tip end 21 and its upper end supports a bolt 47, which in turn carries a hollow disk shaped heating chamber 48 having the side walls 49 and 50. The wall 49 has formed therewith the heat protecting ear 51. A spiral spring 52 in the chamber 48 has one end secured to the bolt 47 and its other end extends through an opening 54 in the circumferential wall of the chamber 48. A pin 53 is carried by the end of the spring 52 that extends through the opening 54. A bolt 55 extends from the cap 44 and the bracket 56 has one end fastened to the bolt.

handle 65 extends from'the bracket 56.

To operate the burner the gas is lighted at the gas tip 22 and the handle 65 is raised and maintained in its raised position to keep the valve 40 off of its seat 35 for a few seconds. The heat from the gas tip'22 will expand and elongate the spring 52 in a few seconds. The handle can then be released and the valve 40 will remain oil of its seat 35 to allow the gas to pass through the opening 31, port 30 and opening 32 on its way to the gas tip 22 through the tip end 21. If for any reason the gas is extinguished the spiral spring 52 cools and contracts and thereby forces down the bracket 56 and seats the valve 40 on its seat 35 closing off the gas supply.

The ofliceof the ear 51 is to prevent overheating the spring 52 and the brack t 56 at their junction.

I-Iaving described my invention what I desire to secure by Letters Patent and claim is: v

The combination in a gas burner of a tip end having a chamber extending to the outside thereof, a top wall and a bottom wall for the chamber, a valve spindle extending through to bottom wall, a valve secured to the spindle and coacting with a valve seat formed in the wall of the tip end, a bypass port formed in the wall of the tip end extending around said chamber, a spring located to be heated by the heat of the light from the gas tip and connections between the said spring and valve.
